I got an LG14 plasma today and it buzzes! It happens even if I disconnect all inputs so I'm guessing it's to do with the power supply or something like that. If I put my head behind the screen it is very noticeable, if I have the volume low to medium and sit 10 feet away I can still hear it. My girlfriend says she can't hear it as long as there is some other background noise or there is sound coming out of the speakers. Has anyone else noticed this problem with this model or the LG17? I am wondering whether to get it swapped out or just return it for a refund and get an LG17 instead. Otherwise I am enjoying the display very much, I can't bear to look at my old 28 inch widescreen now! TIA.
